ATI's Catalyst 12.8 has some installer problems where it doesn't completely supersede the previous driver you had installed. You may have run into them.

This was the information ATI returned to me when I reported the problem to them (I'm not a fan of automatic cleaners, but this is verbatim from them):

Uninstall all ATI drivers and any other video card software from the Add or Remove Programs and Features in the Windows Control Panel. Click on AMD Catalyst install manager, click change and then choose the option to express remove all AMD software.

Try using a driver cleaner program to make sure the drivers are removed: Please keep in mind that the (Driver Cleaner / Driver Sweeper are 3rd party software and not supported by AMD) please refer to their websites for instruction and guidance.

If the problem still exists please try installing your video card in another PC or try installing another video card in your PC if possible, this will tell us if the issue follows the graphics card or the PC.

Or test your other hardware like RAM, CPU , USB devices…etc to make sure they do not create the problem.

If the problem still exists please download the Belarc Advisor - a free system diagnostics, system information and benchmarking to create a problem report as described: In HTML format and attach file to e-mail.

2. Remove ATI driver from add/remove programs then remove the control panel from add/remove programs

3. Reboot into safe mode (F8 during boot up)

4. On reboot into safe mode WinXP SP1/SP2 will auto detect and install drivers. Just let it do its thing. If you can cancel out of the auto install hardware wizard then skip the rest and run Driver Cleaner! If you can NOT cancel out of auto detect wizard then...

PS crashes at different times when I am working in the 3D area. I'm making a logo, its very simple, just two letters and an ampersand (&) "J&J" the background is a textured background. I have all three characters extruded. An example of a particular crash is: I open the file, choose a tool say the move tool and boom it crashes. Should I get my money back?
